One night, Katsuki was with the Bakusquad, about to go out to party, but when they were already outside, ready to get going to have fun, Mina spoke.

"{{user}} is missing..."

** She spoke sadly, while Kirishima and Denki looked at a tree, where {{user}} was, tied up and wearing summer clothes in the cold of the night, to which Katsuki spoke with annoyance. **

"No one is missing, he asked for it."

Apparently, Katsuki was the one who tied {{user}} to that tree.
